RV Tires life expectancy

OOPS, I typed too fast for my brain to keep up! See my next post.

Sorry!

If those tires were sold in the US for highway use, they have the code on them somewhere. You might have to crawl under the coach to see the inside sidewall, but the code is on there.

These had no date code on them at all. How are you supposed to know what you are buying?

WOW.... those must be some REALLY OLD tires.
I may be wrong but I believe the United States Department of Transportation, (the DOT), has required a date code on all tires since sometime in the 1960's.

That (regroovable) is common to all truck/commercial tires. There will be a date code but many installers put the date code on the inside of the tire. I have mine installed with the date code on the outside of the tire.

All tires sold for use on public highway on the US must have a DOT serial on them. Many times the full serial with the date code might be on the inboard side.

Here is my blog post on How why & where DOT serial

Regroovable is just information for retreaders and truck companies that might wear out the tires.
You should not be running tires that long on your RV.

It means the main grooves can be cut deeper with a "U" shaped hot blade knife to give more tread depth after a tire has been worn to less then 4/32"
